DETAILED DESCRIPTION When a user uses some uplink sensitive services (such as E-mail, pictures, video uploads, etc.), a large amount of uplink data is generated, which requires a large load on the uplink carrier frequency. At this time, if the cell accessed by the user equipment is heavily loaded in the uplink direction, when a large amount of uplink data is sent, a delay occurs, and data transmission efficiency is low, which affects the user experience.

In order to solve the problem of low data transmission efficiency when the amount of uplink data is large, multi-cell HSUPA cooperation can be used to transmit uplink data, and BP: data is transmitted through cooperation of multiple uplink cells to reduce the data load on a single cell. But how to activate multiple cells simultaneously to send uplink data when the UE generates a large amount of uplink data, and how to disconnect the part of the cells that are not needed to be used when the user equipment does not need to send uplink data to multiple cells to reduce the carrier frequency Interference, how to dynamically adjust the number of uplink cells used by the UE, and perform reasonable activation and deactivation management. The implementation method is not provided in the prior art.

Embodiment 1 of the present invention will be described below with reference to the accompanying drawings.

Embodiment 1 of the present invention provides an uplink carrier frequency management method to dynamically adjust the number of uplink cells. As shown in FIG. 1, the method may include:

Step 101: Obtain a state switching decision indication of an uplink secondary serving cell.

Step 102: Perform state switching on the at least one uplink secondary serving serving cell according to the state switching decision indication. Step 103: notify the communication peer end of the state of the at least one uplink secondary serving serving cell.

The uplink carrier frequency management method provided in this embodiment triggers state switching management of an uplink secondary serving cell by using a state switching decision indication, and completes state switching of at least one uplink secondary serving cell according to the state switching decision indication, and The status of the at least one uplink secondary serving cell is notified to the communication peer, which provides a working mechanism for the data transmission to implement multi-cell cooperation in the uplink direction, and solves the problem that the uplink carrier frequency management cannot be performed on the multi-cell HSUPA cooperation.

Embodiment 2 of the present invention will be described below with reference to the accompanying drawings.

When the user equipment needs to send a large amount of uplink data to the base station, the multiple cells can cooperate to establish a connection with the cells in multiple carrier frequencies, and simultaneously on the primary carrier cell and one or more uplink secondary carrier serving cells. Send uplink data and increase the bandwidth for sending upstream data. When the user equipment does not need to use the multi-cell cooperative to send the uplink data, the unused cell can be deactivated, the number of cells used by the user equipment is reduced, and interference between different frequency cells is reduced. This example is described by using a dual cell cooperatively to send uplink data as an example. For convenience of description, The dual-cells are respectively named as the uplink primary carrier cell and the uplink secondary carrier serving cell, and the uplink primary carrier cell works on the uplink primary carrier frequency, and the uplink secondary carrier serving cell works on the uplink secondary carrier carrier frequency; All the cells of the primary carrier constitute an uplink active carrier cell active set, and the active set includes one uplink primary carrier serving cell; all cells working on the same uplink secondary carrier form an uplink secondary carrier activated set, and the active set includes an uplink auxiliary. Carrying a service cell. In this embodiment, the uplink secondary serving cell may be an auxiliary E-DCH serving cell. The uplink carrier frequency management method provided in this embodiment is as shown in FIG. 2, and includes:

Step 201: The base station receives a state switching decision indication.

When the base station is connected to the network, the RNC (Radio Network Controller) sends a status switch decision indication to the base station, instructing the base station to perform measurement and judgment according to the state handover decision indication, and complete the uplink auxiliary service. Activation and deactivation of the cell.

In this step, the base station receives a state handover decision indication, and the state handover decision indicates carrying decision control, where the decision control includes multiple decision objects, such as data volume control, uplink load, and SG (Serving Grant) control ( The uplink load and the auxiliary uplink SG are all judgment objects related to the uplink signal quality. Since there are many types of decision objects in the communication field, the judgment objects are not listed here, and the judgment object is used to measure whether other auxiliary carriers need to be activated. The cell transmits uplink data; the decision control further includes a plurality of decision parameters, such as a measurement time window (the measurement time window is a measurement interval, and the measurement value measured for a certain decision object is taken within the measurement interval. Average value), the activation threshold (that is, the condition that triggers the activation of other secondary cells, including the user uplink data volume and the uplink signal quality standard, when the user uplink data amount exceeds the activation threshold, and the signal quality of the uplink secondary serving cell When the uplink signal quality standard is reached, the uplink auxiliary service can be activated. The cell performs the uplink data transmission, and the deactivation threshold (that is, the condition for triggering the deactivation of the uplink auxiliary serving cell, including the uplink data amount of the user and the uplink signal quality standard, when the uplink data amount of the user is lower than the deactivation threshold, or When the signal quality of the uplink secondary carrier serving cell does not meet the uplink signal quality standard, the uplink secondary carrier serving cell may be deactivated, and the uplink secondary carrier serving cell may be stopped for uplink data transmission.

The activation threshold and the deactivation threshold may be one value or two different values, and the activation threshold may be slightly higher than the deactivation threshold. When the data transmission amount is between the activation threshold and the deactivation threshold, the threshold is not changed. The status of the uplink secondary serving cell.

It should be noted that, in other embodiments of the present invention, two or more uplink secondary serving cells may be activated for transmission of uplink data of the user. In this case, the activation threshold may include multiple thresholds, and the thresholds are sequentially incremented, for example, the threshold values are 5M, 8M, and 10M, respectively. The increase of the user uplink data volume is a gradual process. When the uplink data volume of the user exceeds 5M, the first uplink secondary serving cell is activated, and when it exceeds 8M, it is activated. The second uplink secondary carrier serving cell activates the third uplink secondary carrier serving cell over 10M, and so on, multiple uplink secondary carrier serving cells work on different uplink auxiliary carrier frequencies; or may include only one gate The limit value, after exceeding the threshold, activates other cells on the available secondary carrier frequencies of the current base station of the user equipment as the uplink secondary serving cell.

Corresponding to multiple uplink activation thresholds, the deactivation threshold may also include multiple thresholds, for example, the threshold values are 5M, 8M, and 10M, respectively, and the user uplink data reduction is also a gradual process. When the uplink data volume of the user is less than 10M, an uplink secondary carrier serving cell is deactivated. When the uplink data is lower than 8M, an uplink secondary carrier serving cell is activated, and so on. Of course, when there are multiple uplink activation thresholds. There may be only one deactivation threshold. For example, the activation thresholds are 5M, 8M, and 10M, respectively, but there is only one deactivation threshold, such as 5M. When the uplink data volume is lower than 5M, all uplink auxiliary service cells are used. Perform deactivation.

Using the uplink carrier frequency management method provided in this embodiment, the principle of activating an uplink secondary carrier serving cell or deactivating an uplink secondary carrier serving cell in the case of multi-cell cooperation, and activating the uplink secondary carrier serving cell or deactivating in cooperation with the dual cell The principle of the uplink auxiliary carrier cell is substantially the same and will not be described again.

Step 202: The base station performs a state switching decision, and sends a state switching request message to the user equipment. In this step, the base station performs a handover instruction according to the state received in step 201, performs measurement on the relevant decision object, and compares the measurement result with the judgment. The parameters are compared to determine if the uplink secondary carrier cell needs to be activated.

If the user equipment is in the dual-cell uplink cooperative activation state, that is, the user equipment is connected to the base station through the primary carrier cell and the uplink secondary carrier serving cell at the same time, and the uplink data is sent. In a measurement window, as long as the measured value of one control object satisfies the deactivation threshold, the amount of uplink data transmitted by the secondary carrier serving cell is small, or the signal quality of the uplink secondary serving cell is poor, and the uplink signal cannot be satisfied. The quality standard, the base station performs the deactivation operation on the uplink secondary carrier serving cell, specifically: sending a deactivation request message to the user equipment, where the deactivation request message carries the uplink auxiliary carrier frequency carrier where the uplink secondary carrier serving cell is located The identifier (the identifier may be a frequency value of the uplink auxiliary carrier frequency, or may be a unique identifier allocated by the system for the uplink secondary carrier frequency), requesting the user equipment to stop sending uplink through the uplink secondary carrier serving cell data. The deactivation request message may be a physical layer message, and may be carried in a channel such as HS-SCCH, E-AGCH, E-RGCH or other physical layer; or may be a MAC PDU.

If the user equipment is in the dual-cell uplink cooperative deactivation state, that is, the user equipment currently only sends uplink data through the primary carrier cell. In a measurement window, the base station performs measurement according to the information in the state handover decision indication, and performs measurement on the cell except all the carrier frequencies except the carrier frequency of the primary carrier, if the uplink data volume of the user equipment exceeds the activation threshold. And the signal quality of the secondary serving cell satisfies the signal quality standard, and then the cell performs an activation operation, and allocates a part of uplink data of the primary carrier cell to the uplink secondary carrier cell for transmission. The activation operation is specifically: The station sends an activation request message to the user equipment, where the activation request message carries the identifier of the uplink secondary carrier frequency of the selected uplink secondary serving cell (the identifier may be the frequency value of the uplink secondary carrier frequency, or Is the unique identifier assigned by the system to the uplink auxiliary carrier frequency). The activation request message may be a physical layer message, or may be

MAC PDU.

Step 203: The user equipment performs state switching.

In this step, the user equipment performs a corresponding state switching operation on the uplink secondary serving serving cell according to the message received in step 202.

If the user equipment receives the deactivation request message, the user equipment acquires the corresponding uplink secondary carrier serving cell according to the identifier of the uplink secondary carrier carrier frequency of the uplink secondary carrier serving cell carried in the activation request message, and stops at the uplink auxiliary network. The uplink data is sent on the serving cell, for example, the uplink data transmission and the uplink DPCCH transmission on the uplink secondary serving cell are stopped.

If the user equipment receives the activation request message, the user equipment acquires the corresponding uplink secondary carrier serving cell according to the identifier of the uplink secondary carrier carrier frequency of the uplink secondary carrier serving cell carried in the activation request message, and starts on the uplink secondary carrier serving cell. Uplink data transmission and uplink DPCCH transmission.

Step 204: The user equipment sends a status switch response message.

In this step, after performing the state switching operation on the uplink secondary serving cell, the user equipment sends a state switching response to the base station to notify the base station of the operation result.

The physical channel of the status switch response message sent by the user equipment may be an HS-DPCCH or other physical layer channel. If the user equipment receives the deactivation request message in step 203, the user equipment sends a deactivation response message to the base station after performing the deactivation operation on the uplink secondary serving cell.

If the user equipment receives the activation request message in step 203, the user equipment sends an activation response message to the base station after performing an activation operation on the uplink secondary carrier cell.

Step 205: The base station notifies the RNC of the status of the uplink secondary serving cell.

In this step, the base station sends a status notification message to the RNC according to the status switching response received in step 204, where the status notification message carries the status of the uplink secondary serving cell.

Step 206: The RNC forwards the state of the uplink secondary serving cell to other cells in the secondary active set that are not aware of the state change of the uplink secondary serving cell.

All cells operating on the same carrier frequency under the base station constitute an active set, which is a set of cells operating on the uplink secondary carrier frequency and connected to the user equipment. The RNC sends a control message to the user equipment, where the control message carries the cell identifiers of the multiple cells, and the measurement needs to be performed on the cells, and the user equipment is finished. After the measurement is performed, the measurement result is reported to the RNC, and the RNC determines, according to the result, which cells are added to the auxiliary activation set of the user equipment, and selects the cell with the best signal quality as the uplink secondary carrier serving cell. The auxiliary activation set is notified to the user equipment, specifically, the uplink auxiliary carrier frequency that is notified to the user equipment of the secondary activation set and the cell included in the secondary activation set. When the user equipment establishes a connection with the base station through the uplink secondary carrier cell, the connection is actually established with all the cells in the secondary activated set. All the uplink cells in the secondary active set can carry the uplink data or the synchronization control signal carrying the uplink DPCCH. After the uplink secondary serving cell is deactivated, the user equipment stops the uplink DPCCH in the cell in the secondary activated set. When all the cells in the secondary active set are synchronized, the link synchronization failure between the cell and the user equipment is considered to be unsuccessful due to the failure to detect the DPCCH signal, and the synchronization failure may cause the network side to release the cell and the The radio link to which the user equipment is connected, so that the cell can no longer share the uplink data of the primary carrier cell as the uplink secondary serving cell.

In order to solve the above problem, in this step, the RNC notifies the uplink auxiliary carrier to activate the state of the uplink auxiliary carrier frequency of all cells except the uplink secondary carrier serving cell, and send a status notification message, if the uplink After the state of the secondary serving cell is switched from the active state to the deactivated state, all the cells in the secondary activated active set acquire the current state of the uplink secondary serving cell, and then stop the uplink DPCCH detection, and the user equipment and the secondary device are not The connections of the active-carrying centralized cells are all disconnected, so as to subsequently select other cells except the uplink secondary carrier serving cell to perform an activation operation.

The step is an optional step. If the RNC does not notify the other cells in the auxiliary activation set except the uplink secondary serving cell after the uplink secondary serving cell is deactivated, when the auxiliary active set is activated, When the cell detects that the link synchronization fails, the cell reports a Radiol ink Failure to the RNC. However, since the RNC already knows the status of the uplink secondary serving cell, the received link does not delete the corresponding link, and the wireless link between the user equipment and the secondary activated set cell is also maintained.

In the uplink carrier frequency management method provided by the embodiment, the RNC sends a state handover decision indication, and the base station performs measurement and determination according to the state handover decision indication. When the dual cell uplink cooperation is required, the uplink support is determined according to the measurement result. a serving cell, instructing the user equipment to perform an activation operation on the uplink secondary serving serving cell; when the uplink secondary serving serving cell does not need to send data, instructing the user equipment to perform the deactivation operation on the uplink secondary serving serving cell, implementing the dual cell In the uplink cooperation mode, flexible management of the uplink secondary carrier serving cell enables uplink data transmission using multi-cell HSUPA cooperation. And after the operation is completed, notifying the RNC of the status of the uplink secondary serving cell, and further, the RNC notifying the secondary activation group of the state of the uplink secondary serving cell other than the uplink secondary serving cell, Synchronization of the cell state reduces the amount of data processed by the RNC, maintains an effective link, and saves network resources. The measurement and judgment are completed by the base station, and the time required to obtain the uplink data information is short. The system is highly efficient.

In this step, the base station sends a status notification message to the RNC, where the status notification message carries the status of the uplink secondary serving service cell.

Step 406: The RNC forwards, to the other cells in the secondary active set in which the uplink secondary serving cell status is changed, the state of the uplink secondary serving cell.

When the user equipment establishes a connection with the base station through the uplink secondary serving cell, the connection is actually established with all the cells in the secondary active set, and only one cell with the best signal quality is selected as the uplink secondary serving cell. All the uplink cells in the secondary active set send the uplink data, but the base station only receives the uplink data sent by the uplink secondary carrier serving cell; all the cells in the secondary activated active set perform link detection, specifically uplink DPCCH synchronous detection. When the base station detects that a certain link is disconnected, the base station sends a Radiol ink Failure to the RNC to notify that the link is disconnected.

When the user equipment deactivates the uplink secondary serving cell, the uplink DPCCH detection of the cell connection in the secondary activation set is actually stopped, and the connection between the user equipment and the secondary activated active cell is not completed. Disconnect, in order to subsequently select other cells for activation.

The step is an optional step. If the RNC does not notify the other cells in the auxiliary activation set except the uplink secondary serving cell after the uplink secondary serving cell is deactivated, when the auxiliary active set is activated, When the cell detects that the synchronization fails, it reports the Radiolink Failure to the RNC. However, since the RNC already knows the status of the uplink secondary serving cell, the received downlink packet fails, the corresponding link is not deleted, and the user equipment is also implemented. The secondary carrier activates the maintenance of the wireless link between the set cells.

In the uplink carrier frequency management method provided by the embodiment, the RNC sends a state switching decision indication, and the user equipment performs measurement and determination according to the state switching decision indication. When dual cell uplink cooperation is required, the appropriate uplink auxiliary is selected according to the measurement result. The serving cell is activated, and the cell is activated. When the uplink auxiliary carrier cell is not required to send data, the uplink auxiliary carrier cell is deactivated, and the uplink auxiliary mode is implemented in the dual cell uplink cooperation mode. The flexible management of the serving cell solves the problem that the uplink data transmission using the multi-cell HSUPA cooperation cannot be realized. And after the base station instructs the user equipment to perform the state switching operation, the base station notifies the RNC of the status of the uplink secondary serving cell, and further, the RNC notifies the auxiliary activation set that the other cells except the uplink secondary serving cell are the uplink auxiliary. The state of the serving cell realizes the synchronization of the cell state, reduces the amount of data processed by the RNC, maintains an effective link, and saves network resources. The measurement and judgment are completed by the user equipment, and the time required to obtain the uplink information is short, and the system efficiency is high.

Embodiment 5 of the present invention will be described below with reference to the accompanying drawings.

This embodiment provides an uplink carrier frequency management method, as shown in FIG. 5, including:

Step 501: The user equipment receives a state switching decision indication.

When the user equipment is added to the network through the base station, the RNC (Radio Network Controller) sends a status switch decision indication to the user equipment, and instructs the user equipment to perform measurement and determination according to the state handover decision indication. The uplink secondary carrier serving cell in the embodiment of the present invention is specifically an auxiliary E-DCH cell.

Step 502: The user equipment performs a state switching decision, and sends a state switching request message to the RNC. In this step, the user equipment performs a handover decision indication according to the state received in step 401, performs measurement on the relevant decision object, and compares the measurement result with the The decision parameters are compared to determine if the uplink secondary carrier cell needs to be activated. In this step, the specific process of the state switching decision by the user equipment is similar to the process of the state switching decision by the base station in the embodiment shown in FIG. 2, and details are not described herein again.

If the user equipment determines to perform the deactivation operation on the uplink secondary serving cell, the deactivation request message is sent to the RNC, where the deactivation request message carries the identifier of the uplink secondary carrier frequency carrier where the serving cell of the uplink secondary carrier is located (the identifier may be It is a frequency value of the uplink auxiliary carrier frequency, and may be a unique identifier allocated by the system for the uplink secondary carrier frequency. The user equipment is requested to stop sending uplink data by using the uplink secondary serving cell. The deactivation request message is carried in an RRC message; it may also be a MAC PDU. If the user equipment determines to perform an activation operation on the uplink secondary serving cell, the device sends an activation request message to the RNC, where the activation request message carries the identifier of the uplink secondary carrier frequency carrier where the selected uplink secondary serving cell is located (the identifier may be The frequency value of the uplink auxiliary carrier frequency may also be a unique identifier assigned by the system to the uplink secondary carrier frequency. The activation request message may be a physical layer message or a MAC PDU.

Step 503: The RNC forwards the state switching request message to the base station.

In this step, the RNC forwards the activation request message or the deactivation request message received in step 502 to the base station.

Optionally, the RNC may directly send a status switch response message to the user equipment, and trigger a state switch of the user equipment to the uplink secondary serving cell.

Step 504: The base station sends a status switch response message to the user equipment by using a physical layer message.

Step 505: The user equipment performs state switching.

In this step, the user equipment performs a corresponding state switching operation on the uplink secondary serving serving cell after receiving the state switching response according to the determination result of step 502.

If the user equipment receives the deactivation response message, the user equipment stops transmitting uplink data on the uplink secondary serving cell, such as stopping uplink data transmission and uplink DPCCH transmission on the uplink secondary serving cell.

If the user equipment receives the activation response message, the user equipment carries the uplink secondary identifier according to the activation request message, and enables uplink data transmission and uplink DPCCH transmission on the uplink secondary serving cell.

Step 506: The RNC forwards the state of the uplink secondary serving cell to all the cells in the secondary active set. When the user equipment establishes a connection with the base station by using the uplink secondary serving cell, the RNC is actually all with the auxiliary activated set. The cell establishes a connection, and only selects one cell with the best signal quality as the uplink secondary carrier serving cell, and sends the uplink data through all the uplink cells in the secondary activated set, but the base station only receives the uplink supplementary serving cell. Uplink data; all cells in the secondary active set perform link detection, specifically uplink DPCCH synchronization detection. When the base station detects that a certain link synchronization fails, the base station sends a Radiol ink Failure notification to the RNC to notify the synchronization failure.

After receiving the status notification message, the base station forwards the status notification message to all other cells in the secondary active set.

If the user equipment performs the deactivation operation on the uplink secondary serving cell, the all the cells in the secondary active set will stop the synchronous detection of the uplink DPCCH; if the user equipment activates the uplink secondary serving cell, Then all cells in the secondary active set will enable synchronous detection of the DPCCH.

The step is an optional step. If the RNC does not notify the other cells in the auxiliary activation set except the uplink secondary serving cell after the uplink secondary serving cell is deactivated, when the auxiliary active set is activated, When the cell detects that the link synchronization fails, the cell reports a Radiolink Failure to the RNC. However, since the RNC already knows the status of the uplink secondary serving cell, the received Radiolink Failure is discarded, and the corresponding link is not deleted, and the wireless link between the user equipment and the secondary activated set cell is also maintained.

Embodiment 6 of the present invention will be described below with reference to the accompanying drawings.

This embodiment provides an uplink carrier frequency management method, as shown in FIG. 6, including:

Step 601: The user equipment receives a state switching decision indication.

When the user equipment is added to the network through the base station, the RNC (Radio Network Controller) sends a status switch decision indication to the user equipment, and instructs the user equipment to perform measurement and determination according to the state handover decision indication. The uplink secondary carrier serving cell in the embodiment is an auxiliary E-DCH cell.

In the embodiment of the present invention, the state switching decision indication is specifically a measurement control message. In this step, the user equipment receives the measurement control, where the measurement control carries multiple measurement objects, such as uplink transmission power measurement of the user equipment, and auxiliary uplink wireless. Signal quality measurement, UE uplink data volume measurement, etc., may also include the following parameters: measurement time window, event reporting threshold, reporting period, and the like. Each measurement object in the above measurement control is independent of each other, and what kind of measurement object is sent to the mobile phone is determined by the network side. For details of the decision control, refer to the embodiment shown in FIG. 2 . The description in the description will not be repeated.

Step 602: The user equipment sends a measurement report to the RNC.

In this step, the user equipment performs measurement according to the measurement control received in step 601, and generates a measurement report by the measurement result, and sends the measurement report to the RNC.

Step 603: The RNC performs a state switching decision.

In this step, the RNC stores the decision parameters required for determining activation and deactivation. In this step, the RNC receives the measurement report according to step 602, and compares the measurement result with the decision parameter to determine whether the uplink auxiliary needs to be activated. Service area.

If the user equipment is in the dual-cell uplink cooperative activation state, that is, the user equipment is connected to the base station through the primary carrier cell and the uplink secondary carrier serving cell at the same time, and the uplink data is sent. In a measurement window, as long as the measured value of one control object satisfies the deactivation threshold, the amount of uplink data transmitted by the secondary carrier serving cell is small, or the signal quality of the uplink secondary serving cell is poor, and the uplink signal cannot be satisfied. a quality standard, the RNC sends a deactivation request message to the base station, where the deactivation request message carries an identifier of an uplink secondary carrier frequency carrier where the uplink secondary carrier serving cell is located (the identifier may be a frequency value of the uplink secondary carrier frequency carrier) The user equipment is requested to stop sending uplink data by using the uplink secondary carrier cell.

If the user equipment is in the dual-cell uplink cooperative deactivation state, that is, the user equipment currently only sends uplink data through the primary carrier cell. In a measurement window, if the uplink data volume of the user equipment exceeds the activation threshold, and the signal quality of the uplink secondary serving cell satisfies the uplink signal quality standard, the RNC sends an activation request message to the base station, where the activation request message carries The identifier of the uplink secondary carrier frequency of the selected uplink secondary carrier cell (the identifier may be the frequency value of the uplink secondary carrier frequency, or may be the unique identifier allocated by the system for the uplink secondary carrier frequency) . The activation request message may be an NBAP (Node B Application Part) message.

Step 604: The base station forwards a state switching request message to the user equipment.

In this step, the base station forwards the activation request message or the deactivation request message received in step 603 to the user equipment, where the activation request message or the deactivation request message is carried in the physical layer channel.

Step 605: The user equipment performs state switching.

In this step, after receiving the status switching request message, the user equipment performs a corresponding state switching operation on the uplink secondary serving serving cell. For the specific process of the state switching of the user equipment, refer to the description in the embodiment shown in FIG. 2, and details are not described herein.

If the user equipment receives the deactivation request message, the user equipment stops transmitting uplink data on the uplink secondary serving cell, such as stopping the E-DCH transmission of the secondary carrier and transmitting the uplink DPCCH. If the user equipment receives the activation request message, the user equipment enables E-DCH transmission and uplink on the uplink secondary serving cell according to the identifier of the uplink secondary carrier frequency carrier where the uplink secondary serving cell is carried in the activation request message. The launch of the DPCCH.

Step 606: The user equipment sends a status switch response message to the base station.

In this step, the user equipment sends a status switch response message to the base station by using a physical layer message, and if the user equipment performs an activation operation on the uplink secondary serving cell, an activation response message is sent; The serving cell performs a deactivation operation, and then sends a deactivation response message.

Step 607: The RNC forwards the state of the uplink secondary serving cell to all the cells in the secondary active set. When the user equipment establishes a connection with the base station by using the uplink secondary serving cell, the RNC is actually all the active secondary set. The cell establishes a connection, and the uplink data is sent by all the uplink cells in the auxiliary activation set, but the base station only receives the uplink data sent by the uplink secondary carrier serving cell; all the cells in the secondary activated active set perform link detection. Specifically, the uplink DPCCH synchronization detection is performed. When the base station detects that a certain link synchronization fails, the base station sends a Radiolink Failure notification to the RNC, and the synchronization fails.

When the user equipment deactivates the uplink secondary serving cell, the uplink DPCCH detection of the cell connection in the secondary activation set is actually stopped, and the connection between the user equipment and the secondary activated active cell is not completed. And disconnecting, so as to subsequently select, in the auxiliary activation group, other cells except the uplink secondary serving cell to perform an activation operation.

The step is an optional step. If the RNC does not notify the other cells in the auxiliary activation set except the uplink secondary serving cell after the uplink secondary serving cell is deactivated, when the auxiliary active set is activated, When the cell detects that the link synchronization fails, the cell reports a Radiolink Failure to the RNC. However, since the RNC already knows the status of the uplink secondary serving cell, the received link does not delete the corresponding link, and the wireless link between the user equipment and the secondary activated set cell is also maintained.

In other embodiments of the present invention, the RNC may also send measurement control to the base station to implement the method. The implementation process is similar to the process in which the user equipment reports the measurement report in this embodiment, and details are not described herein.

In the uplink carrier frequency management method provided by the embodiment, the RNC sends the measurement control to the user equipment, and the user equipment reports the measurement result required to activate the uplink secondary serving cell, and the RNC determines the measurement result according to the measurement result. When the cell is in uplink cooperation, the uplink auxiliary secondary serving cell is selected according to the measurement result, and the user equipment is instructed to perform an activation operation on the cell; when the uplink auxiliary carrier cell is not required to send data, the uplink secondary serving cell is deactivated. The operation realizes flexible management of the uplink auxiliary carrier cell by the user equipment in the dual cell uplink cooperation mode, and solves the problem that the uplink data transmission using the multi-cell HSUPA cooperation cannot be realized.

If the user equipment is in the dual-cell uplink cooperative activation state, that is, the user equipment is connected to the base station through the primary carrier cell and the uplink secondary carrier serving cell at the same time, and the uplink data is sent. In a measurement window, as long as the measured value of one control object satisfies the deactivation threshold, the amount of data in the uplink is small, or the signal quality of the uplink secondary serving cell is poor, and the uplink signal quality standard cannot be met, the RNC is to the user. All the base stations in the device auxiliary activation group send a deactivation request message, requesting the user equipment to stop sending uplink data through the uplink secondary serving cell.

If the user equipment is in the dual-cell uplink cooperative deactivation state, the user equipment currently only sends uplink data through the primary carrier cell. In a measurement window, if the uplink data volume of the user equipment exceeds the activation threshold, and the uplink secondary serving cell satisfies the carrier load standard (for example, the signal quality meets the uplink signal quality standard), the RNC sends an activation request message to the base station. The activation request message may be an NBAP (Node B Application Part) message or an FP (Frame Protocol) frame.

For the non-uplink secondary carrier serving cell in the secondary active set, after receiving the deactivation request message, the synchronous detection of the uplink DPCCH and the reception of the data are stopped. The deactivation request message may be an NBAP (Node B Application Part) message or an FP (Frame Protocol) frame.

The step of the RNC sending a deactivation request message to the non-serving cell in the secondary active set is an optional step.

In this step, the base station forwards the activation request message or the deactivation request message received in step 802 to the user equipment, where the activation request message or the deactivation request message is carried in a physical layer channel, such as HS-SCCH (High Speed Shared Control Channel). , high speed shared control channel).

Step 804: The user equipment performs state switching.

In this step, the user equipment performs a corresponding state switching operation on the uplink secondary serving serving cell according to the state switching request message received in step 803.

If the user equipment receives the activation request message, the E-DCH transmission on the uplink secondary serving cell and the transmission of the uplink DPCCH are enabled.

In this step, the user equipment sends a status switch response message to the base station through the physical layer message, indicating that the corresponding operation has been performed according to the status switch message sent by the base station.

In addition, if the RNC performs the state handover decision in step 802, and finds that the primary carrier cell satisfies the deactivation condition (eg, the signal quality cannot meet the normal communication requirement), a reconfiguration decision is made to reconfigure the primary carrier cell and the uplink for the user equipment. The secondary serving cell can also switch the user equipment from the dual cell cooperation state to the single carrier mode.

The decision information may include user equipment uplink transmit power measurement, uplink radio signal quality measurement, uplink carrier load measurement, user equipment uplink data buffer status or data to be sent.

In this embodiment, the base station stores the decision parameters required for determining activation and deactivation, and the base station compares the measurement result carried in the measurement report with the uplink load information of the cell level on the base station with the decision parameter to determine whether activation is required. The uplink assists the serving cell, and sends a state switching request message to the RNC according to the judgment result. For the specific process of the state handover decision, refer to the description in the embodiment shown in FIG. 2, and details are not described herein again.

If the base station decides to perform the deactivation operation on the secondary serving cell, the base station sends a deactivation request message to the RNC to request the RNC to perform a state switching decision, requesting to stop the user equipment from transmitting the uplink data through the uplink secondary serving cell.

The RNC may perform a state switching decision according to the state switching request message sent by the base station and the activation set information of the user equipment. The RNC sends the result of the decision to the serving base station or the user equipment in the manner of the activation request message or the deactivation request message to all the cells in the active set. For the specific procedure, refer to step 802 in the eighth embodiment of the present invention.

Steps 903 to 905 in the embodiment of the present invention are substantially the same as steps 803 to 805 in the eighth embodiment of the present invention, and details are not described herein again.

In addition, if the RNC performs a state handover decision in step 902, it is found that the primary carrier cell satisfies the deactivation condition, The reconfiguration decision is made to reconfigure the primary carrier cell and the uplink secondary serving serving cell for the user equipment, and may also switch the user equipment from the dual cell cooperative state to the single carrier mode.

This embodiment provides an uplink carrier frequency management method, as shown in FIG. 10, including:

Step 1001: The base station performs a state switching decision.

In this step, the base station performs a state switching decision according to the measurement report reported by the user equipment, such as the scheduling information of the primary carrier cell and the secondary carrier cell, and the current load and signal quality of the cell.

If the base station determines that the secondary serving cell needs to be deactivated, it sends a deactivation request message to the user equipment; if the base station determines that the secondary serving cell needs to be activated, it sends an activation request message to the user equipment.

The activation request message and the deactivation request message may be carried on a physical channel, such as an HS-SCCH channel. The steps 1002 to 1003 in the embodiment of the present invention are basically the same as the steps 804 to 805 in the eighth embodiment of the present invention, and details are not described herein again.

If the activation of the secondary serving cell is performed in the foregoing process, the RNC and the other cells in the secondary activation set are notified to the active secondary cell. The specific steps are as follows:

Step 1004: The base station forwards a state switch response message to the RNC.

In this step, the base station forwards the state switching response message sent by the user received in step 1003 to the RNC to notify the RNC user equipment of the current working state.

When the uplink secondary cell is deactivated, the RNC attaches the active set to the user equipment. The uplink secondary serving cell sends a status notification message, where the status notification message may be NBAP (Node B) Application Part) message or FP (Frame Protocol).

If the state switch response message is a deactivation response message, the non-uplink secondary non-serving cell in the secondary active set stops receiving synchronization detection and data reception of the uplink DPCCH after receiving the message.

In addition, if the RNC does not notify other cells except the uplink secondary serving cell after the uplink secondary serving cell is deactivated, the cell in the secondary active set detects the link. When the synchronization fails, the Radiol ink Failure is reported to the RNC. However, since the RNC already knows the status of the uplink secondary serving cell, it does not respond to the received Radiolink Failure, does not delete the corresponding link, and also implements the maintenance of the wireless link between the user equipment and the secondary activated set cell.

In the uplink carrier frequency management method provided by the embodiment, the base station determines whether the uplink secondary carrier serving cell needs to be activated according to the measurement report reported by the user equipment.
